Layer‐wise Theory and Finite Elements for Laminated Poroelastic Shells

Research output: Contribution to journalArticleResearchpeer-review

Abstract

In order to consider growing expectations on vibro-acoustic performance of products within the design process, reliable simulation tools are necessary. In this paper, we present a approach for the simulation of laminated shells composed of elastic and poroelastic layers. We assume that the shell is given by a parametrization, which allows us to work witn the exact geometry. The three-dimensional problem is reduced to a two-dimensional one, by choosing a set of through-the-thickness functions for each quantity and through-the-thickness integration. The implemented high order finite element approach for the reduced problem on the reference surface relays on hierarchical shape functions. In a numerical example, we show the influence of poroelastic materials attached to a aluminium shell. (© 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
